[ovirt-users] Re: gluster service on the cluster is unchecked on hci cluster

Well... not yet. Check if the engine detects the volumes and verify again that all glustereventsd work. I would even consider restarting the engine, just to be on the safe side.

What is your oVirt version ? Maybe an update could solve your problem.

So I am interested what could make that checkbox inactive... well, on db side it looks like cluster has gluster_service disabled... engine=# select virt_service, gluster_service from cluster;   virt_service | gluster_service --------------+-----------------   t            | f (1 row) still don't know why the checkbox is disabled. Would it be safe to enabled gluster_service directly in db? I suppose no... :-) Cheers, Jiri > >> For the vdsm, you can always run >> '/usr/libexec/vdsm/vdsmd_init_common.sh --pre-start' which is executed >> by the vdsmd.service before every start (ExecStartPre stanza) and see >> if it complains about something. > > [root@ovirt-hci03 <mailto:root@ovirt-hci03> ~]# /usr/libexec/vdsm/vdsmd_init_common.sh --pre-start > vdsm: Running mkdirs > vdsm: Running configure_vdsm_logs > vdsm: Running run_init_hooks > vdsm: Running check_is_configured > sanlock is configured for vdsm > lvm is configured for vdsm > abrt is already configured for vdsm > Managed volume database is already configured > Current revision of multipath.conf detected, preserving > libvirt is already configured for vdsm > vdsm: Running validate_configuration > SUCCESS: ssl configured to true.
